Abstract

EL DIODO SE INCORPORA DE UNA MANERA FIJA SOBRE EL EJE OPTICO DE UNA LENTE PORTADORA. LA LENTE PORTADORA CONSISTE EN UNA PARTE FRONTAL CON UNA SUPERFICIE TRANSVERSAL EXTERNA, FORMADA CONCAVA HACIA LA LUZ EMITIDA Y UNA PARTE LONGITUDINAL PARA INCORPORA EL DIODO. LA PARTE LONGITUDINAL TIENE SU SUPERFICIE LONGITUDINAL FORMADA CONCAVA HACIA EL DIODO. LA SUPERFICIE TRANSVERSAL CONCAVA ESTA RODEADA POR UN SISTEMA TRANSVERSAL EXTERNO. LA SUPERFICIE LONGITUDINAL CONCAVA ESTA DISPUESTA PARA REFLEJAR LOS RAYOS DE LUZ EMITIDOS POR EL DIODO HACIA LA SUPERFICIE ADICIONAL TRANSVERSAL EXTERNA QUE ESTA DISPUESTA PARA TRANSMITIR LOS RAYOS DE LUZ HACIA FUERA EN UNA DIRECCION LONGITUDINAL.
